## Questions & Answers

**Q: Will this work with DC power?**
A: Yes it does work with DC and the rating is noted on the label inside the switch cover.

**Q: Is this what we would use to "replace the check valve"? Our water is getting sucked back into well & electricity bill is outrageous.**
A: No. This is. The device that cuts the pump off and on. The check valve looks like a piece of pipe and is installed close to the pump.

**Q: Will this switch work off 12 volts DC? 
If so, what is the amp rating and wiring scheme?**
A: the pressure switch will work with 12 to 32 volt DC current up to a 1/4 HP motor.   the wiring is the same 
for this type of installation too.  We can not provide more electrical details due to liability.

**Q: Is this a direct replacement for a type: sk2 sta-rite switch?**
A: Sorry, I am not totally familiar with sk2 sta-rite type switch. This a standard 40-60 press switch.
